Empowering Next-Gen AI with High-Performance Memory Solutions

DEEPX is a leading innovator in the rapidly transforming Generative AI (GenAI) landscape, specializing in edge AI solutions. The company’s mission is to enable smarter, faster, and more efficient AI technologies that can be integrated seamlessly into everyday applications. DEEPX’s product portfolio includes advanced AI processors designed to deliver exceptional performance while adhering to stringent power and area requirements for edge computing applications.

DEEPX’s value proposition lies in its ability to bridge the gap between high-powered AI applications and the constraints of edge devices, offering solutions that maximize efficiency without compromising performance. While model training typically occurs in powerful data centers, where vast amounts of data are processed to create sophisticated Large Language Models (LLM), the true value of AI often lies in deploying these models on the edge for inferencing. There these models are applied in real-time to generate insights and drive actions. DEEPX is dedicated to capturing this value at the edge, ensuring that AI solutions are not only robust but also highly responsive and efficient in real-world applications. DEEPX focuses on key markets such as autonomous mobility, industrial automation, smart cities, and consumer electronics, where edge AI plays a crucial role in enhancing functionality and enabling real-time decision-making.

Evaluating the right memory for edge AI applications

As DEEPX developed its next-generation AI processor, the demands for a high-performance memory interface became evident. Their system architecture required a memory solution that could deliver excellent bandwidth to support AI computational workloads while staying within strict power, performance, and area (PPA) requirements. Additionally, the memory controller needed to ensure reliable operation under diverse workloads while being cost-effective and scalable for mass production.

DEEPX evaluated several memory standards, including GDDR and HBM, but realized that LPDDR5/5x was the ideal choice for their edge AI applications. LPDDR technology provides a compelling balance of high performance and low power consumption at the right price point, making it well-suited for systems that operate in constrained environments such as edge devices. Moreover, LPDDR5/5x offers significant advancements over previous generations, including increased data rates, reduced latency, and enhanced power efficiency, which are critical for optimizing AI processor performance.

After rigorous research and evaluation, DEEPX selected Rambus LPDDR5/5x Controller IP as the memory solution for their AI processor. Several factors influenced this decision:
